Dear colleagues,
 recently I asked for tabulated information on standard
 covalent bond lengths and angles. I got quite a few answers
 and would like to heartily thank for all contributions.
 Below you find a compilation of the information sources
 I have been suggested to use:
 TEXTBOOKS:
 Solomons;
 Morrison & Boyd;
 International Tables of Crystallography, Volume C;
 CRC Handbook of Chemistry (some standard bond lengths);
 CRC Handbook of Chemistry and Physics;
 Structure data of polyatomic molecules, Kuchitsu, K. Ed.
 Springer_Verlag, Berlin, 1992.
 ARTICLES:
 "A Standard Geometrical Model for Compounds of the Main Group Elements H
 Through I", M.R. Peterson and I.G. Csizmadia, J. Mol. Struct. (Theochem),
 vol. 123, pp. 399-412 (1985).
 R. A. Engh and R. Huber  Accurate Bond and Angle Parameters
 for {X}-Ray Protein Structure Refinement Acta. Cryst. A.
 1991, 47, 392-400.
 ONLINE:
 http://www.chem.swin.edu.au/modules/mod2/bondlen.html
 (some standard values)
 FORCEFIELDS:
 MMFF, Tripos
 Up to now, I could not check all the sources,
 but I could get a copy of the International Tables
 of Crystallography, Vol. C, which on pp. 788ff.
 provides extensive information on "average bond
 lengths for bonds involving the elements H to I."
 Again thanks to everybody,
 Maria
